1) Error Handling

EUVDB-ID: #VU63299

Risk: Medium

CVSSv3.1: 4.2 [CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:L/I:L/A:N/E:U/RL:O/RC:C]

CVE-ID: CVE-2022-25762

CWE-ID: CWE-388 - Error Handling

Exploit availability: No

Description

The vulnerability allows a remote attacker to gain access to sensitive information.

The vulnerability exists due to an error when handling WebSocket connections. If a web application sends a WebSocket message concurrently with the WebSocket connection closing, it is possible that the application will continue to use the socket after it has been closed. As a result, subsequent connections can use the same object concurrently and share data and/or other errors.
